title: Inelastic constitutive modeling for blood vessels based on viscoplasticity.
abstract: A transversely isotropic inelastic constitutive model based on the concept of internal variable theories is proposed to describe the hysteresis loops of blood vessels under cyclic loading by taking account of loading path dependence as well as loading rate dependence. The comparison of the numerical results with literature shows that the present model can describe the anisotropic inelastic mechanical behavior well.
